Heater Guard – Nano Size

The Heater Guard – Nano Size is a compact perforated plastic sleeve designed to fit the slender profile of nano and small heaters typically found in 5–30 litre aquariums. Standard full-size heater guards are too bulky for nano heaters and can impede water flow in tight spaces, making this smaller variant essential for protecting delicate inhabitants.

Neocaridina and caridina shrimp are attracted to the warmth radiating from heater elements and will climb the tube, risking being trapped between the element and the guard in oversized designs. The nano guard's precise sizing prevents this while still maintaining a protective barrier. The open mesh allows full water circulation without compromising heat transfer efficiency.

A must-have accessory for shrimp keepers, breeders using small spawning tanks, and anyone running a nano setup with a small submersible heater.
